MSD Blaster GM Internal HEI Module

MSD Blaster GM Internal HEI Module
Product List Loading:  wait
MSD has created a high energy ignition module to replace the weak stock module of GM HEI Ignitions (with an internal coil). The new High Energy Module and Coil work together to improve spark energy output or the stock GM HEI distributors. In fact, they are capable of delivering powerful sparks up to 9,000 rpm.
The High Energy Module is the only true aftermarket high performance module built for HEI distributors. The MSD Module holds a more precise timing and dwell control at high rpm where other modules actually retard the timing. It also provided higher coil drive currents than the stock module. This saturates the coil faster which gives you more spark energy at top speeds. To improve the performance of your stock HEI Distributor, the bolt-on improvements of MSD's High Energy Module and Coil are the way to go.
